Solution:

Suppose The income of a person is $12,000 and amount spent on family expenditure , fare,and outing are 6,000 and 1,000 and $ 500 respectively.So, Ratio of income and money spent can be represented on a bar, which helps in observing as well as predicting the solution easily.

Now, coming to rate problem  If the two quantities are proportional suppose  Speed of a person in different interval of time is given ,and we represent these distances on a bar Diagram, we can easily calculate as well as predict the solution of these kind of problems.

So,ratio and rate are actually the same thing ,that is they gives a fixed value when two quantities are in comparison ,and when plotted on a bar diagram helps in determining as well as predicting the solution of the problem.

<span>Bar graph display directly the varibales which are the rate and ratio of the numbers to visualize and display the results, these contrasting the different outcomes. On the contrary, histogram is used in grouped frequency parameters. Moreover, as little as the given five parameters or data set this will be ineffective and will result to a bar graph only and basically, the suited option is the aforementioned vertical graph to display the numbers. To expound on the definition of histogram it is used when the frequency is grouped. For example the data set of 1-5, 6-10, 11-15 and 16-20 this now can be used and applied to illustrate histogram because of the number and quantity of the given data.<span>

Input values for which g(x)=2 ?
Molodets [167]

Answer:

y = 2

Step-by-step explanation:

If someone gives you an function that says f(x) = x + 2, that is the same thing as saying y = x + 2. The f(x) part is just to represent that it is a function of x.

Determine the equation of the following polyromial that passes through point (0,6).
Ostrovityanka [42]

Answer:

Cubic polynomial has zeros at x=−1x=−1 and 22, is tangent to x−x−axis at x=−1x=−1, and passes through the point (0,−6)(0,−6).

So cubic polynomial has double zero at x=−1x=−1, and single zero at x=2x=2

f(x)=a(x+1)2(x−2)f(x)=a(x+1)2(x−2)

f(0)=−6f(0)=−6

a(1)(−2)=−6a(1)(−2)=−6

a=3a=3

f(x)=3(x+1)2(x−2)f(x)=3(x+1)2(x−2)

f(x)=3x3−9x−6

Step-by-step explanation:

let AC be length of ladder and BC be distance between ladder and wall and angle be theta

Now,

costheta=BC/AC

THETA =COS^-1(3÷8)

THETA=COS^-1(0.375)

THETA=67.97 DEGREE

Find S10 for -1 + -7 + -13 + -19
Alex777 [14]
First we find the common difference...to do this we subtract the first term from the second term. -7 - (-1) = -7 + 1 = -6

now we are going to find the 10th term
an = a1 + (n-1)*d <== formula for finding any term in arithmetic series
a1 = 1st term, d = common difference, n = term we want to find
now we sub
a10 = -1 + (10 -1) * -6
a10 = -1 + (9 * -6)
a10 = -1 - 54 
a10 = - 55

now we will find the sum
Sn = (n (a1+ an)) / 2 <== formula for finding the sum 
S10 = (10(-1 - 55))/2
S10 = (10(-56) / 2
S10 = -560/2
S10 = - 280

so the sum of the first 10 numbers is -280
